SenseCAP LoRaWAN Data Logger and Rain Gauge

moonlight · November 7, 2022, 2:29am

I have a SenseCAP LoRaWAN Data Logger connected to the Hydreon Rain Gauge RG-15 and connected to TTN. Does the TTN-Payload-Decoder/decoder_new-v3.js at master · Seeed-Solution/TTN-Payload-Decoder · GitHub support this combination.

I am getting what looks like invalid data in my payload

The Seeed guys have answered my query in a separate email. I will paste here as it may help others with the same problem.

Please use this decoder of the link:

github.com

Seeed-Solution/TTN-Payload-Decoder/blob/master/SenseCAP_LoRaWAN_V2_Decoder_For_TTN.js

/**
 * Entry, decoder.js
 */
function decodeUplink (input, port) {
  // data split

  var bytes = input['bytes']
  // init
  bytes = bytes2HexString(bytes)
    .toLocaleUpperCase()

  let result = {
    'err': 0, 'payload': bytes, 'valid': true, messages: []
  }
  let splitArray = dataSplit(bytes)
  // data decoder
  let decoderArray = []
  for (let i = 0; i < splitArray.length; i++) {
    let item = splitArray[i]
    let dataId = item.dataId
